Currently I measure salinity with a refractometer. Temperature with thermostat in tank and on heater display and with a food grade digital thermometer. Just ordered a Hannah ULR Phosphate checker literally like 30 minutes ago.
I currently measure salinity with a refractometer, temperature with my Inkbird controller and phosphate with the Nyos kit. The Hanna checkers would be a great upgrade!
I’ve been using the Hanna phosphate checker for a few years now and is the only way I test phosphate. It’s simple, reagents are cheap, and it’s very accurate.
As for salinity I use a refractometer. I’ve been interested in the Hanna handheld salinity checker since it was released. I can’t wait to get my hands on one.
1, 2, 3 and Bonus done. I don’t currently have an aquarium but I’m looking to set one up this summer. Therefore I currently don’t test for these things.
